We aren't doctors here and can't diagnose. It doesn't sound like a yeast infection to me, but I'm not a doctor. I don't know what it is or if it was anything at all. I'm not sure candida can survive in that place. As for fungal infections, the usual ones would be where you have pubic hair and where you sweat, and the most common is ringworm. If medication doesn't work, you can try natural medicine for it. But without a diagnosis, there can't be any recommendations. The medication used for candida is quite different than that used to treat ringworm, for example.
